MACHINE FOR REMOVING SN OW.

Application filed September 20, 1926. Serial No. 136,608.

The object of this invention is to provide a machine for removing snow from streets and highways, and especially to include in such a machine one or more scoop frames each carrying a blade or scraper and each mounting an elevating conveyor driven from a transverse shaft with reference to which the frames are angularly movable.

A further object is to provide a trans-.

versely movable conveyor and a loading conveyor, and means for controlling the angular position or inclination of the loading conveyor, the latter being adapted to discharge to a wagon, or to the side of a highway or along suburban or country roads.

A further object is to provide for imparting the necessary drive to all moving elements, to provide for guiding the machine, and to provide for varying the angular position of the scoop frames carrying the blades or scrapers.

l/Vith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illustrated and claimed, it being understood that modifications may be made within the scope of the claim, without de parting from the spirit of the invention.

In the drawings forming part of this application,

Figure 1 shows the machine in side elevation.

Figure 2 is a top plan view.

Figure 3 is a view in longitudinal section, with parts in elevation.

Figure t shows the relative position of the transverse conveyor andthe loading conveyor, and the mounting means for these elements.

A main frame includes the side bars and 11, the rear transverse elements 12 and 13, and forward transverse bars 1 1 and 15, the latter constituting a conveyor frame. A narrow platform is designated 16, and below bars 1 1 and 15 longitudinally extending bars Hand 18 are mounted along side of side bars 10 and 11 which extend practically the full length of the frame. The forward wheels 19 and 20 are carried by axles 21 mounted in bearing brackets 22 which are secured to the elements 10 and 11 and 17 and 18, the relative position of these features of the construction being clearly illustrated in Figure 4, and further illustrated in Figure 3.

Rear wheel 23 is mounted in a forked standard 24 having rigidly mounted near its upper end a segment 25 meshing with gear wheel. 26 on steering shaft 27 controlled by wheel 28. A drivers seat is shown at 29 and a draft evener is designated 30, being mounted by a pin or bolt 31 near the rear of the main frame. The singletrces 32 and are connected in any well known manner with the element 30.

An engine 35 is mounted on the transverse elements 36 connected with the side bars 10 and 11 of the main frame. The hood for the engine is designated 37, and a radiator is shown at 38.

Engine shaft 39' carries gear wheel 40 meshing with gear wheel etl on shaft 42 mounted in bearings below the main frame. Shaft 412 imparts drive to line shaft 13 thru universal joint 4 1, and a similar joint 15 permits shaft 43 to impart drive to shaft 16 mounting rigidly thereon a bevelled gear wheel 17. This wheel 17 has formed thereon or connected tl'ierewith, a wheel 18, and said wheel 17 meshes with a bevelled gear wheel 19 on transverse shaft 50.

The shaft carries a wheel 51 for driv ing belt or other flexible device 52 passing around wheel 53 on shaft 5 1. The shaft last named extends across the front portion of the machine, and imparts drive to the forward conveyors mentioned below. Wheel 18 drives chain 55 and double sprocket wheel 56 on shaft 57. Sprocket wheels 58 and 59 on this shaft 57, drive horizontal conveyor 60, extending transversely of the machine and adapted to cooperate with loading conveyor 61 driven from shaft 62 mounting sprocket wheel 63 driven by chain 6 1 pass ing over the sprocket wheel 56 on shaft 57 before referred to.

Frame 65 of the loading conveyor 61 is supported by hangers 66 movable angularly about axial element 67, and the elevation of the outer end of the frame 65 and the loading conveyor is determined by arms 67 each provided with a series of apertures at (59, the arms being adjustably retained by engaging device or devices 69 passing thru an arch brace 70 held in part by brace 71.

Forward frames or scoop frames 7 5 mount V and the latter are adapted to swing with reference to the shaft, the conveyors 80, 81 including chains 82 driven by. sprocket wheels 83 rigid with shaft 54.

' A rock shaft 84 is mounted in bearings 85,

and the arms 86 on this shaft bear on the under side of the scoop frames for controlling the inclination thereof. The construction disclosed permits independent elevation of theframes if they meet obstructions.

The shaft 84 is rocked by crank arm 87 connected with flexible element 88 passing around pulleys 89 and controlled by hand lever90, mounted near the seat of the driver. One of the rotatable elements of the transverse conveyor 80 is-adjusted, for tensioning the conveyor, by shifting the bearing 91 of said rotatable element, by means of bolt 92 held by lock nut 93 which engages a stationary element 9 1 thru which the bolt passes.

The snow passes over blades 77, passes thence to the forward conveyors 80 and 81, and thereafter to the transverse conveyor (it) from which it is carried to loading conveyor 61 for transfer to a wagon or truck, or for deposit at the side of a roadway, as circumstances may determine.

Having thus described the invention, what I claim is:

In a machine of the class described, a main frame, pivotally mounted frames extending forwardly thereof, the frames including], lateral extensions constituting scoops, a'blade extending across the forward end of each pivoted frame, shoes connected with the blade and extending under the forward end of each of the pivoted frames, a rock shaft and arms carried by the shaft and having slidahle engagement with the under sides of the pivoted frames, permitting independent elevation of the frames due to obstructions, operating means connected with the rock shaft, conveying means mounted in the pivoted frames and between the scooplike extensions, and means for receiving material from the conveying means,

In testimony whereof I aflix my signature.
